Accidentally Famous (Men of Midnight Dreams #1)
Celia Blyth, Alexandra Ainsworth

The whole world knows who you are . . . but you've forgotten everything since high school.
When Caleb wakes up in a glamorous clinic in California, he''s a changed man. His once-scrawny body is toned, his now-white teeth gleam, and everyone looks at him in adoration. Caleb shouldn't even be in the US--he's English and has never traveled farther than London.
Somehow Caleb transformed from an eighteen-year-old, sexually questioning, reclusive high school student who spent his free time composing and practicing music in his parents' shabby council flat to become a world famous rock star with adoring fans and his own mansion in Beverly Hills.
Caleb bravely tries to fit into his new life as he recovers from his amnesia. But who is the handsome young Latino publicity manager who visits him in the hospital? Why does everyone think Caleb is straight? What has Caleb forgotten? And will he ever remember?
